if the music is older, and not from the US, it's often not on spotify. Versions matter too - even for some mainstream bands their B sides/acoustic/live versions just aren't on spotify or youtube. Album metadata for spotify is garbage too - it just isn't an adequate replacement for a record collection.
I do use a spotify subscription, but for me it's a tool for playlist generation and music discovery.

I recently set up Sonarr and Radarr on my home server and I'm loving it....
